To aZZ whom t may concern:

Be it known that 1, CLARENCE C. NELLE,

a citizen of the United States, residing at Cold Brook, in the' countyof Herkimer, State of New Yorlr, have invented certain new and usefulImprovements in Radiator Caps;I and 1 do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others 1o skilled inthe art to which it appertains to make anduse the same.

This invention relates to new and useful improvements in closures andparticularly to closures for the filling tubes of automobile radiators.

rilhe filling tube of the ordinary radiator is so constructed that it isnecessary to entirely remove the cap from the filling tube, and theneither drop the cap into the pocket of a garment or lay it downsomewhere, with the obvious danger ot the same being lost or dropping inthe dirt, so that the threads will become closed or clogged and carrythe deposit into the water within the radiator.

Une object of this invention is to provide a cap for a radiator fillingtube which does not have t0 be removed from the tube, but which has amovably mounted portion arranged to be swung` open when the radiator isto be filled.

Another object is to provide a cap of this character having a caparranged to screw into the filling tube and a hingedly mount* ed coverarranged to be swung upwardly for filling the radiator, and which hasmeans for holding it against accidental opening movement. i

Il further object is to provide a filling cap of this character having astrainer to prevent the entrance of dust, dirt or other foreign matterwith the water when the radiator is being` filled.

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accompanying drawing.

1n the drawing:

Figure 1 is an elevation of a radiator cap, made in accordance with theinvention, and seated within the filling tube of a radiator, the fillingtube being in section.

Figure 2 is a view of the same parts shown in Figure 1, but with thccover swung into open position.

Figure 3 is a vertical central sectional view through the cap in a planeparallel to that of Figures 1 and 2.

Referring particularly to the accompanying drawing` 10 represents theinteriorly threaded filling tube of the radiator ll, in connection withwhich the'present invention is used.

rllhe radiator cap includes a body in the form ot a ring lf2, having theexternal threaded portion 13, which is engaged in the filling tube 10.rlFhe upper portion of the body is of less diameter than the threadedportion, and has a smooth exterior 14.

At one point in this smooth faced portion 14e there is a notch 15, andAsecured within this notch is hinge 16. Connected to this hinge is thesmooth-faced dange 17 of the cover 17, which flange is of slightlygreater diameter than the portion 11i and arranged to snugly embracethis latter portion when brought down thereon. rilhe @over portion 17has a hand hold 18 which is grasped to unscrew the device from thefilling tube, when it is desired to'remove the same from the fillingtube. 1n the Outer face of the portion la, diametrically opposite to thehinge, there is formed a small boss 18 which is arranged to snap into arecess 19, formed in the inner face ot the flange 17', to hold the outerpart against accidental opening movement. Vfhen the cap is properlyscrewed down into the filling tube this cover 17 will lie above theupper end of the body 12 ot the cap so that said cover may be swungopen, when desired but which is held from accidental opening by the boss1S.

A screen 19 .is secured across the lower end of the tube so as toprevent the entrance of dust, cirt or other foreign substances whichmight pass in with the water when thc radiator is being filled.
